Not really. Technically Bungie was “indie” after the Activision split and before being bought out by Sony and some of the issues circulating the news today were the same management issues they had when they were “indie”.
Worker-owned is a term rooted in socialism. It means the majority stake (ideologically 100%) of the company is collectively owned by the workers. Thus it means the workers decide what the company does and how they will do it. If an indie company has an owner, who makes the decisions, and employees, who don’t have a say in those decisions, then that’s not really a worker-owned company.
